In Multimode Function (U64) (G Dataflow)

session in

The resource to be used.

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error

error in contains an error

If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

offset

The offset, in bytes, of the location to read from.

This function accepts a 32- or 64-bit unsigned integer as input. The type of resource determines how offset specifies the offset.

INSTR Specific--The offset for an INSTR Resource is the offset address relative to the device's allocated address base for the corresponding address space that was specified. For example, if address space specifies VXI/VME A16, offset specifies the offset from the logical address base address of the VXI device specified. If address space specifies VXI/VME A24, A32, or A64, offset specifies the offset from the base address of the VXI device's memory space allocated by the VXI Resource Manager within VXI/VME A24, A32, or A64.

address space

The following table lists the valid entries for specifying address space:

Name

Value

Description

VXI/VME A16

1

The A16 address space of a VXI or VME device.

VXI/VME A24

2

The A24 address space of a VXI or VME device.

VXI/VME A32

3

The A32 address space of a VXI or VME device.

VXI/VME A64

4

The A64 address space of a VXI or VME device.

PXI Memory Allocations

9

A physical, locally allocated address space.

PXI Configuration

10

The PXI configuration address space.

PXI BAR0 - PXI BAR5

11-16

PXI memory or I/O address space 0 through 5.

Default: VXI/VME A16

session out

The resource to which a VISA session is opened.

This output also includes the class for the session, which matches that of session in.

error out

Error information.

The node produces this output according to standard error behavior.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

next offset

The next byte offset after the data is read from the given address space.

value

The read data.
